Lindsey Vonn was released from a hospital in Colorado on Wednesday, although details of her illness remain unclear and there is no indication of when she can begin skiing again.

"Lindsey is feeling much better today and has been released from the hospital," Vonn's publicist Lewis Kay wrote in an email. "She is resting comfortably at home. Doctors are still working to determine what specifically was the cause of her illness but thankfully she has responded well to their treatment."

Kay added that "we do not know when she will be able to return to the mountain and will update as her health improves."

The four-time overall World Cup champion and Olympic gold medallist in downhill was admitted to the hospital in Vail on Monday and stayed two nights.

On Tuesday, Kay said Vonn was "awaiting results from diagnostic testing for severe intestinal pain," but his latest statement did not specify the reason for the hospitalization.

Her next races are the giant slalom and slalom in Aspen on Thanksgiving weekend, followed by speed events in Lake Louise, Alberta, her most successful stop on the circuit.

Vonn's ski technician, Heinz Haemmerle, told The Associated Press on Tuesday that Vonn has visited the hospital two or three times over the past week.

Haemmerle, who prepares Vonn's Head skis and has been on hand in Colorado awaiting her recovery, said that Vonn hasn't trained since going out in the second run of the season-opening giant slalom on Oct. 27 in Soelden, Austria.

Haemmerle said that Vonn told him she "has pain all over her body and that her bones are hurting."

Haemmerle declined to offer an update when contacted by the AP on Wednesday.

Vonn recently requested to compete in a men's downhill race, only to be rejected by the International Ski Federation. She was hoping to enter the men's race Nov. 24 at Lake Louise, Alberta. Had she been allowed to compete against the men, Vonn would have missed the two women's races in Aspen, Colorado, because they take place the same weekend.

Vonn skipped a slalom in Levi, Finland, last weekend, although Haemmerle said that was their plan to gain more training for Aspen even before the illness.
